COMBINED REFRIGERATOR AND FILTER- Specification of Letters Patent.

Patented June 11, 1907.

Application filed June 26, 1906- Serial No. 267,300-

lb all whoirt iifmay concern.-

,Be'it known that I, JOHN Y. ARNoT, a citizen of the United States,residing at Oak- "having an upwardly extending flang 'land, in thecounty of Alameda and State of California, have invented certain new anduseful Improvements in a Combined Refrigerator and Filter, of which thefollowing is a specification.

This invention relates to a refrigerator and water cooler, the object ofthe invention being to provide an apparatus of this character by meansof which articles of food may be maintained cool without the use of ice,and which will furthermore afford a supply of filtered drinking, water.y

In the accompanying'drawing, Figure 1 is a front elevation of the aparatus; Fig. 2 is a vertical section thereof; Fig. 3 is a horizontalsection on the'line AA of Fig. 1; Fig. 4 is a horizontal section on theline BB of eferring to the drawings, 1 represents a suitable base,preferably rectangular in form, e 2. Upon .said base is supported, byblocks 3, a

\ casing or refrigerator 4, having a bottom 5,

and side walls 6, preferably made of artificial stone, and a top 7preferably made of wood. Within the rece tacle so formed is a food box8,'falso prefera ly made of artificial stone, supported ,upon osts 9 ofthe same material. pThis box 8 1s closed at the top and bottom and onthree sides, but opens at the front into the side of the main casing 4where outward it is closed by a swinging door 10, of the ordinaryconstruction of an ice box door, aving a metallic shell 11 filled withmineral 001 or other insulating material 12. Between the box 8 and thetop ofthe refrigerator are four walls or fpartitions 13 which slopeslightly the refrigerator and are formed. of porous stone of such natureas to ermit water to percolate slowly therethroug Each wall at the topis formed with a number of small channels 14 to admit of ventilationover the surface of {the .pvater, there bein thus providedfreecirculation between t e chamber 15 formed by said walls and theremainder of the interior of the casin 4 outside the box 8. The top ofthis charm er 15 is closed b a cover 16 filled with mineral wool or oter suitable material, which cover can be raised by handles 17. In themiddle of this lid is a funnel shaped cavity 18 which is closed by a omthe top of the box to the top of.

poured into the chamber 15. 19 is centrally perforated to permit thepassage of the stem 20 of a float 21, the level of the top of the stemindicating the level ofthe water in. the chamber, and thejnecessityofreplenishing the chamber with water.

stopper 19, by removing which water can be: The stopper The waterercolating throu h the porous walls of the c amber15 is art y evaporatedon the outside .of said Wal s, thereby reducing the temperatureof thewater, and of the whole interior of the refrigerator, thus enablingarticles of food placed in the box to be preserved without the use ofice. The water vapor escaping through the apertures 23, shown in dottedlines. Any excess of water not thus evaporated dro s'down into the lowerportion of the refrigerator whence it can be drawn off from. time totime by a faucet 22. This water having assed through the porous walls ofthe chem er 15 thoroughly filtered, and in fit condition for drinking,can be drawn off through the faucet 22.

This apparatus is ofgreat value in warm climates and in districts farremoved from ice houses and in which'ice is diflicult to obtain,especially where the water is of an inferior quality, as it not onlyacts as a refrigerator, cooling articles placed therein, but purifiesthe water furnished as the refrigerating agent.

1. An apparatus of the character described, comprising a suitablecasing, porous walls within the casing inclosing a water chamber, a foodbox within the casing the top of which forms the bottom of said chamber,means for supporting said food box at a distance from the interior wallsof the casing, said casing beingconstructed to collect the waterfiltered .the interior walls of the casing, said casing beingconstructed to collect the water filtered through said porous walls, acentrally perfoseams rated stopper for closing the supply opening I handin the presence of tWo subscribing Witto said Water-chamber, the wallshaving latnesses. eral openings at their tops to permit air to passtherethrough, and means for drawing oil I JOHN O 5 the Water filteredthrough said porous Walls, Witnesses: substantially as described.'FRANCIS M.
